Hi, I used mediawriter to successfully write the standard F38 ISO to a usb stick but when I boot from it I get:
Invalid image
Failed to read header: Unsupported
Failed to load image: Unsupported
start_image() returned Unsupported
I found this post which suggests a workaround: https://www.reddit.com/r/RockyLinux/comments/r49er0/comment/hs6mll2/?utm_source=share&utm_medium=web2x&context=3
Essentially the above link says:
- Get into /<USB_Stick>/EFI/BOOT, delete the original BOOTX64.EFI and BOOTIA32.EFI.
- Rename grubx64.efi and grubia32.efi to BOOTX64.EFI and BOOTIA32.EFI respectively.
- Boot your system with this USB stick in UEFI mode and you should be able to boot into the installer
So, I mounted the ISO, copied the contents to my hard drive and renamed the files as above.
My question is: What command line options for mkisofs should I use to recreate the ISO image?
